![]() Using the Accept and Content-Type headers together to describe what can be understood by the client, and what was actually sent, is called Content Negotiation. It allows the client to indicate what kind of content is acceptable, which is another way of allowing the client to specify what kind of content it actually knows how to handle. This allows the target to understand how to decode this content. It is used to describe what format the data being delivered in the body of a request or a response is in. It is possible to inspect $_SERVER to see what the User-Agent header was set to. The User-Agent header gives information about the client making the HTTP request and usually includes information about the software client. Others might be specific to either a request or a response. Many of the headers you see in HTTP make sense in both requests and responses. It is possible to see what kind of request was made to a PHP script acting as a server by inspecting the $_SERVER value, which indicates which verb was used in the request. These requests shouldn’t be repeated or bookmarked, which is why your browser warns you when it is resubmitting data. In contrast to GET requests, a POST request is one that does cause change on the server that handles the request. For example, a GET request is used when filling in a search web form, which should always use GET. URLs used with GET can be bookmarked, they can be called as many times as needed, and the request should not affect change to the data it accesses. $data = array("name" => "Alex", "email" => = curl_init($url) Ĭurl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data)) Ĭurl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')) Ĭurl_setopt($ch, CURLOPT_RETURNTRANSFER, true) Also, set a Content-Type header, which indicates to the server what format the body data is in. To make a POST request, set the CURLOPT_POST option to 1, and pass the data you want to send as an array to the CURLOPT_POSTFIELDS option. curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE) In most cases, this option should be used to capture the response rather than letting PHP echo it as it happens. The CURLOPT_RETURNTRANSFER option is to true, which causes Curl to return the results of the HTTP request rather than output them. curl doesnt send the Expect header unless the post data is over a certain size, your sample code does not send an Expect header either way. Set the CURLOPT_URL option with the $url variable passed into the function: curl_setopt($ch, CURLOPT_URL, $url) The curl_setopt() function is used to set many different options on the Curl. Execute and fetch data from server or send data to server.Using curl in PHP is very simple process: You can use Curl to make all kinds of HTTP requests, including sending custom headers, sending body data, and using different verbs to make your request. It allows you to connect with other URLs and use their responses in your code. How To Make HTTP Requests in PHP - curl() Function
